Refactor: Remove outdated availability and Swift version guards

google-labs-jules[bot] · google-labs-jules[bot] · commit 9146fb911377 · 2025-06-20T16:07:27.000Z
Analyzed project deployment targets and removed unnecessary @available, #available, and #if swift guards throughout the codebase. - iOS deployment target standardized at 15.0. - macOS deployment target baseline at 11.0. - tvOS deployment target baseline at 15.0. - watchOS deployment target baseline at 7.0. Removed #if swift(>=X.X) blocks by migrating the code for the newer Swift version into the enclosing scope and deleting the #else blocks.
